Metric Conversions for TEAS 7 Questions
Question 1 of 5
How many milliliters are there in 0.5 liters?
Correct Answer: A
Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter is equal to 1000 milliliters. So, 0.5 liters x 1000 = 500 milliliters. Therefore, the correct answer is A: 500 milliliters. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters. B is too small, C is even smaller, and D is a decimal value that does not represent a proper conversion.
Question 2 of 5
Convert 0.75 kilograms to grams.
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 0.75 kg * 1000 = 750 grams. Therefore, choice B (750 grams) is correct. Choice A (75 grams) is incorrect as it is a decimal point off; choice C (7,500 grams) is incorrect as it is off by a factor of 10; and choice D (75,000 grams) is incorrect as it is off by a factor of 100.
Question 3 of 5
What is equivalent to 1 L?
Correct Answer: D
Rationale: The correct answer is D: 1000 milliliters. 1 liter is equivalent to 1000 milliliters. This is because the metric system is based on the powers of 10, so there are 1000 milliliters in 1 liter. Choice A, 1 kilogram, is a unit of mass and not volume. Choice B, 1 quart, is a unit of volume but is not equivalent to 1 liter. Choice C, 1 milliliter, is much smaller than 1 liter, as it would take 1000 milliliters to make up 1 liter.
Question 4 of 5
What is the equivalent of 0.3 mg in mcg?
Correct Answer: A
Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.3 mg would be equal to 0.3 * 1000 = 300 mcg. This makes choice A (300 mcg) the correct answer. Choices B, C, and D are incorrect because they do not apply the correct conversion factor of 1000 to convert from mg to mcg, leading to incorrect values.
Question 5 of 5
Convert 34.5 grams to kilograms (kg).
Correct Answer: A
Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in 1 kilogram. Therefore, 34.5 grams divided by 1000 equals 0.0345 kilograms or 3.45 kg (A). The other choices are incorrect because B is the original value in kg, C is 100 times the value in kg, and D is the original value in grams.
